Gloria R Sue, Chao Long, Gordon K Lee
BACKGROUND: Mastectomy skin necrosis is a significant problem after breast reconstruction. This complication may lead to poor wound healing and need for implant removal, which may delay subsequent oncologic treatment. We sought to characterize factors associated with mastectomy skin necrosis and propose a management algorithm. METHODS: A retrospective review was performed on consecutive patients undergoing implant-based breast reconstruction by the senior author from 2006 through 2015...

BACKGROUND: The usage of internal mammary artery perforators (IMAPs) has been described in autologous breast reconstruction although IMAPS are not yet considered standard recipient vessels. It remains unclear if these vessels can be safely used in large flaps after radiation therapy or in delayed breast reconstruction. METHODS: Over a 2-year period, 515 free flaps for autologous breast reconstruction were performed on 419 patients by 2 surgeons (S1 and S2). In a retrospective analysis, time of reconstruction, ischemia time, flap weight, diameter of couplers, and complications were analyzed...

BACKGROUND AND OBJECTIVE: Brachytherapy is a form of radiation therapy using sealed radiation sources inserted within or in the vicinity of the tumor of, e.g., gynecological, prostate or head- and neck cancers. Accurate dose calculation is a crucial part of the treatment planning. Several reviews have called for clinical software with model-based algorithms that better take into account the effects of patient individual distribution of tissues, source-channel and shielding attenuation than the commonly employed TG-43 formalism which simply map homogeneous water dose distributions onto the patient...

BACKGROUND: Patients with a small breast volume and a relative large lumpectomy volume are at risk of developing severe breast deformity and asymmetry following breast conservation, presenting a unique surgical challenge. METHODS: A series of patients undergoing immediate reconstruction by means of an oncoplastic breast augmentation technique following breast conservation are described. The technique includes local tissue rearrangement and bilateral subpectoral breast augmentation with implants of different sizes and shapes, immediately after lumpectomy for a malignant tumor...

PURPOSE: In 2009, the American Society for Radiation Oncology (ASTRO) published consensus recommendations that stated ductal carcinoma in situ (DCIS) patients were in a "cautionary" group for accelerated partial breast irradiation (APBI) and should not receive APBI outside of a clinical trial. However, very recently, ASTRO placed low-risk DCIS patients in the "suitable" category. Given this recent change, we aimed to use the Surveillance, Epidemiology, and End Results (SEER) database to evaluate past patterns of implantable APBI (IAPBI) utilization in women with DCIS...

BACKGROUND: Since the introduction of nipple-sparing mastectomy as an oncologically safe procedure for the treatment of breast cancer, reconstructive efforts for immediate staged expander/implant reconstruction have focused on submuscular implantation with or without acellular dermal matrix. Suprapectoral reconstruction without acellular dermal matrix has received little attention in the reconstructive literature of nipple-sparing mastectomy. METHODS: Between 2005 and 2015, 155 patients (250 breasts) underwent nipple-sparing mastectomy with prepectoral staged expander/implant reconstruction using thick mastectomy skin flaps without acellular dermal matrix...

The most commonly chosen flaps for delayed breast reconstruction after postmastectomy radiation therapy (PMRT) are abdominal-based free flaps (ABFFs) and pedicled latissimus dorsi (LD) musculocutaneous flaps. The short-and long-term advantages and disadvantages of delayed ABFFs versus LD flaps after PMRT remain unclear. We hypothesized that after PMRT, ABFFs would result in fewer postoperative complications and a lower incidence of revision surgery than LD flaps. METHODS: We retrospectively reviewed a prospectively maintained database of consecutive patients who underwent unilateral, delayed breast reconstruction after PMRT using ABFFs or pedicled LD flaps with implants at the MD Anderson Cancer Center between January 1, 2001, and December 31, 2011...

BACKGROUND: Implant-based breast reconstruction with an acellular dermal matrix is one of the most common procedures performed by plastic surgeons. Although numerous matrices are available, there is little literature comparing them. This study compares the rates of complications between two commonly used products: AlloDerm (human cadaveric) and SurgiMend (fetal bovine) acellular dermal matrices. METHODS: A retrospective review of a single center's 6-year experience was performed for consecutive, immediate breast reconstructions with acellular dermal matrix from 2009 to 2014...

BACKGROUND: The ideal timing of postmastectomy radiation therapy (PMRT) in the setting of two-stage implant-based breast reconstruction remains unclear. In this cohort study, the authors sought to determine whether complication rates differed between patients who received PMRT following tissue expander placement (TE-XRT) and those who received PMRT after exchange for permanent implants (Implant-XRT) utilizing using prospective, multicenter data. METHODS: Eligible patients in the Mastectomy Reconstruction Outcomes Consortium study from 11 institutions across North America were included in the analysis...
